MAY 24-28, 1999 • MINNEAPOLIS, MN
41st CUG ConferenceFinal Program
Welcome to the 1999 CUG Conference!
We are excited to welcome everyone to Minneapolis for the1999 CUG Conference. As the original home of CrayResearch, it seems a fitting place to close out the millenniumand look ahead to the next. We are indeed at the end of anera, as the supercomputing paradigm has shifted from the"big iron" to an HPC world of high-performance commodityprocessors.
The CUG Program Committee has planned an exciting weekof technical sessions and discussions. Add to that good food,a grand night out in the elegant Minnesota History Center,an evening reception hosted by SGI, a special luncheon forCUG newcomers, and a chance to meet with your colleaguesin the comfortable setting of the downtown MinneapolisMarriott City Center Hotel. We think it will be a rewardingand important event for the the CUG community.
The technical program promises to be excellent and weencourage you to peruse the program. In addition, we areexcited to have as keynote speaker Dr. Cherri M. Pancake,Professor of Computer Science at Oregon State University.
Minnesota is called the Land of 10,000 Lakes, and we hopeyou take some extra time to enjoy the environment. Spring
is a beautiful time of year here, and enthusiasm runs high aspeople begin to enjoy the outdoors after a long northernwinter. From the bluffs of the mighty Mississippi River inthe east, to the scenic shores of one of the largest fresh waterlakes in the world (Lake Superior), to the farms and prairiesof the west, Minnesota provides a diverse offering for visi-tors. Whether you like outdoor activities and sports, a quietrespite in the northern woods, or just some time to see thesights in the Twin Cities of Minneapolis and St. Paul, wehope your stay will be memorable.
Minnesota is known for friendly but reserved people, whooften are masters of understatement. To use the words ofGarrison Keillor, well-known Minnesota humorist and hostof national public radio's "A Prairie Home Companion," wethink this conference will be "not too bad," which, translatedfrom understated Minnesota parlance, means it will begreat!

Welcome
To the Members of CUG:
Welcome to the 41st CUG conference on high performance com-putation and visualization. This is your best chance in 1999 toexchange problem-solving information and enjoy professionalinteractions with your fellow users of SGI and CRAY technicalcomputing systems in the birthplace of supercomputing!
Discover how CUG—your user forum on SGI high performancesystems—can be your source for up-to-the-minute informationand insight for that competitive edge you need.
Please, review the Technical Program in the following pages fora truly unique opportunity to experience the "End of an Era ...Eve of a New Millennium."
The CUG Program Committee has assembled a diverse array ofdetail-packed presentations in Tutorials, Keynote and GeneralSessions, Special Interest Group technical presentations andspontaneous "Birds of a Feather" (BOF) discussions.
• Tutorial Sessions on Monday morning—available to youat NO additional charge—are a great opportunity for youto update your technical skills with the help of selectedtechnical experts from SGI and CUG sites.
• The Welcome and Keynote Session, Monday afternoon,starts the countdown. The Keynote Speaker, Cherri Pancake ofOregon State University, is a well-known opinion-leader inHPCC.
• General Sessions during the week provide you with thelatest corporate and technical information from SGI execu-tives, as well as general-interest technical presentations.
• Parallel Technical Sessions each day give you the opportu-nity to focus on the specific knowledge domains of theSpecial Interest Groups (SIGs). Presentations in these ses-sions have been reviewed and selected for you by SIGChairpersons.
• Summit Interactive Sessions on Tuesday and Thursdayeach provide a forum for interaction between CUG andSGI with more time than a Parallel Technical Session andmore focus than a General Session.
• Birds of a Feather (BOF) Sessions, the most dynamicaspect of a CUG conference, are scheduled as needed, andnotices of BOF meetings will be posted near the MessageBoard. You are welcome to organize a BOF session duringthe conference.
• Formal receptions and informal luncheons are among thecountless occasions you will have to exchange informationwith your colleagues from other CUG sites and to collabo-rate with representatives from SGI.
You can see how the Minneapolis CUG Conference offerssomething for everyone during an exciting, educational, andentertaining week as we experience the
End of an Era......Eve of a New Millennium

Program Notes
Special Interest Group (SIG)Meetings
SIGs will hold meetings on Monday that are
open to all interested CUG attendees. They
provide a forum to discuss the future direc-
tion of the SIG, important issues, and talks
of special interest. You are encouraged to
attend any of these open meetings.
Summit Interactive SessionsSummit Interactive Sessions on Tuesday and
Thursday each provide a forum for interac-
tion between CUG and SGI with more time
than a Parallel Technical Session and more
focus than a General Session.
Program Committee MeetingThe Program Committee needs your ideas!
Come to the Open Program Committee
meeting on Thursday to hear about the next
CUG conference and to share your sugges-
tions of how to make each CUG the best one
to date. All conference attendees are invited
and encouraged to attend this open meet-
ing. The CUG Conference Program is the net
result of the combined efforts of all interest-
ed CUG sites. Come to the Program Com-
mittee meeting and make your unique con-
tribution to the next CUG conference!
Video TheaterSupercomputers generate data that, via sci-
entific visualization, can be transformed into
pictures that provide a way for scientists to
understand the information more fully and
quickly. Although the primary purpose of
visualization is to facilitate the discovery
process, scientists are increasingly coming to
rely on it also to present their research con-
clusions. This Friday morning session show-
cases the latest in scientific/engineering
visualization.
Conference Program UpdatesWe anticipate that there will be continuing
changes to the Program schedule. You
should plan to check the Bulletin Boards on
site at CUG each day for schedule changes.
Thank you for your patience and coopera-
tion.
Call for PapersWe encourage you to present a paper at the
CUG 2000 conference in The Netherlands.
Please see the Call for Papers at the end of
this brochure.

Abstracts
Tutorials I–IV 8:30I System Tuning for the Origin2000
Edward Hayes-Hall (SGI)
A focus on the systune parameters. The tutorial
will present a list of the most often used para-
meters (15–20 or so) with descriptions of what
they are and how they interact with other sys-
tune parameters. This will be a technical pre-
sentation for people who know something
about systune and system resources.
II OpenMP
Tom MacDonald (SGI)
OpenMP is a portable shared memory pro-
gramming model with bindings for Fortran, C
and C++. This tutorial will present the major
constructs and features in OpenMP that enable
programmers to write coarse grain, scalable,
shared memory parallel programs. The tutorial
is aimed at users interested in writing parallel
applications or parallelizing existing applica-
tions in Fortran, C and C++.
III Visualization: OpenGL Volumizer
Chikai Ohazama (SGI)
This tutorial will present the basic structure of
OpenGL Volumizer. Details of its use for scien-
tific visualization, and the advantages versus
the disadvantages for using volume rendering,
will be discussed. The mechanics behind Mon-
ster Volumizer and its use will also be
addressed.
IV SV1
Jef Dawson (SGI)
This tutorial will describe the performance
characteristics of the Cray SV1. It is intended to
enable programmers to develop optimization
strategies for their software running on the
SV1.
Tutorials V–VIII 11:00V Performance Tools on the Origin
Alex Poulos (SGI)
As applications grow larger, compiler opti-
mizations more aggressive, processor designs
more sophisticated and system architectures
more scalable, performance analysis is getting
more and more complex. This tutorial will pro-
vide a presentation of SGI’s performance tools
that offer practical solutions helping the users
understand the behavior of their codes and
tune their applications on Origin systems. The
tutorial is targeted toward all audiences. A
Q&A session will follow.
VI Scheduling for the T3E
Jay Blakeborough (SGI)
A presentation of the current state of schedul-
ing for the T3E. A discussion of the solution of
current solved and unsolved problems. Ques-
tions arising from this tutorial will be treated
in a Q&A session later in the meeting.
VII I/ O Tuning
Randy Kreiser (SGI)
How to optimize disk I/O for both SCSI and
Fibre Channel attached disks and XFS File Sys-
tems. To include Optimal File System Block
size determination, whether to stripe and what
the stripe size should be, systune resources
that affect disk I/O performance, performance
aspects of internal vs. external Journal files,
and how to determine the optimal allocation
group count. Some information about specific
computers and OS systems will be presented.
VIII Data Intensive Computing
William Kramer (NERSC)
Data intensive computing is increasingly
important in scientific research, whether for
experimental data analysis and visualization,
or intensive simulation such as climate model-
ing. By integrating high performance computa-
tion, very large data storage, high bandwidth
access, and both local and wide area high-
speed networking, data intensive computing
stretches the technical resources of most archi-
tectures. The synergy of networking and com-
putational initiatives should produce major
improvements in data intensive computing
technology in the next several years. Preparing
for this paradigm shift is the prime motivation
for this tutorial. The tutorial provides an
overview of these issues followed by case stud-
ies that explore in detail different aspects of
research and systems solutions for data inten-
sive computing.

Keynote Address:
They Who Live by the FLOP May Dieby the Flop
Cherri Pancake, Oregon State University
It's definitely not your father's supercomputer
anymore—it's not even like your own super-
computer of just a few years ago. HPC users
don't want to believe that every time they get
familiar with a new type of machine it will be
superceded by something entirely different.
Are they being unrealistic, or are market forces
going to push users to the breaking point? This
presentation will examine trends that have
emerged at HPC vendors, at user sites, and
across the broader computing marketplace to
identify the long-term implications for usabili-
ty. Examples gleaned from hundreds of inter-
views with users and vendors will be used to
show why HPC has evolved to its current
state, and what will be needed for users to
believe that future machines are really "new
and improved."
2A–C Special Interest Group (SIG)Updates (Open Meetings)
4:00 to 6:00These meetings are open to everyone. The
meetings will introduce the SIG leadership,
SGI contacts and basic agenda of the SIG.
Please come and participate. See the Monday
4:00 and 5:00 schedule on page 5 for a list of
SIGs and Chairs.
2A Communications and DataManagement SIG 4:00
Chair: Hartmut Fichtel (DKRZ),
Mass Storage Focus Area Chair: Jeff Terstreip(NCSA)
Networking Focus Area Chair: Hans Mandt (BCS)
This SIG currently consists of the above two
focus areas, and is interested in nearly all
aspects of networking, I/O, and mass storage
(hardware, software, performance, security).
After the SIG restructuring process of last year
this meeting concentrates on compiling input
to get the technical activities going again. The
meeting is open to everyone. Please come and
participate, and give us your technical input.
This is the opportunity to influence the direc-
tion of the SIG and compile questions/com-
ments/criticism to SGI

IRIX Focus Area Chair: Cheryl Wampler (LANL)
Security Focus Area Chair: Virginia Bedford(ARSC)
UNICOS Focus Area Chair: Ingeborg Weidl(MPG)
This session will be of interest to those who
want the inside scoop on SGI’s plans for IRIX,
Unicos, and Security. SGI will discuss their
development plans for IRIX and security and
their retirement plans for Unicos. Will we ever
see NT on SGI high end systems? What about
Linux? Will IRIX support Session Level
Accounting? Will User Resource Limits be inte-
grated into IRIX? SGI will answer these ques-
tions and more in a thumbnail sketch of their
development plans for IRIX, Unicos, and Secu-
rity. Following this 15 minute presentation, we
will discus features we both like and dislike
about the existing products. These will be cate-
gorized and the top likes and dislikes for each
area will be presented to SGI.

Liam Forbes (ARSC)
This paper and talk will cover the first ten
steps ARSC performs to secure a Unix (UNI-
COS or IRIX) machine. This paper is aimed at
system administrators implementing host
based security network-wide or on a single
machine. None of these steps require extra
security packages and have helped us to main-
tain a similar configuration across multiple
platforms and machines.

(SANs).
3C Software Tools 9:30The Integrative Role of COW’s andSupercomputers in Research and Edu-cation Activities
Don Morton (ARSC)
Experiences of researchers and students are
presented in the porting of code between a
cluster of Linux workstations at The University
of Montana and the CRAY T3E at the Arctic
Region Supercomputing Center. We test the
thesis that low-cost workstation environments
may be utilized for training and for developing
and debugging parallel codes which can ulti-
mately be moved to the CRAY T3E with rela-
tive ease for realizing high performance gains.
We further present ideas on how the comput-
ing environments of supercomputers and
COW’s might benefit from more commonality.

Thomas Elken (SGI)
Silicon Graphics was one of the first to employ
nested dissection matrix ordering methods for
reducing the non-zeroes in solving sparse sys-
tems of linear equations. This talk will discuss an
enhancement which uses randomization, parallel
processing, and a long-term memory to improve
the quality of the matrix ordering. This enhance-
ment has been applied to application software
such as ABAQUS and CPLEX and will soon be
part of the SCSL (SGI/CRAY Scientific Library).
5B Networking 2:30Systems Issues in BuildingGigabyte Networks
Joe Gervais (SGI)
System Area Networks require more than a fast

Dean Elling (SGI)
This talk will cover upcoming enhancements to
improve T3E resilience. SGI currently supports
warm booting PEs from the SWS. With the
release of UNICOS/mk 2.0.5, warm booting PEs
from the mainframe will be supported, which
could significantly reduce the time needed to
perform this function. Dynamic PE renumbering
will also be provided. This feature will enable

outline the implementation of single-PE appli-
cations and migrate-on-swap.
7B Applications 9:30Performance of the Parallel ClimateModel on the SGI Origin2000 and the CRAY T3E
Thomas Bettge, Anthony Craig, Rodney James,Warren G. Strand, Jr., and Vincent Wayland(NCAR)
The DOE Parallel Climate Model (PCM) is a
tightly coupled model of the earth’s physical
and dynamic climate system, and includes
fully active components of the atmosphere,
ocean, land, river water, and space. It was
designed for use on the T3E massively parallel
machine architecture, and adapted for use on
the distributed shared memory Origin2000.
The computational design of the PCM, includ-
ing the compromises incorporated to address
conflicting scientific and computational
requirements, priorities, and deadlines, will be
summarized. Performance experiences on both
the T3E and Origin2000 will be presented.

7C User Services 10:00Providing Extra Service: What To DoWith Migrated User Files?
R.K. Owen (NERSC)
When faced with decommissioning our popu-
lar C90 machine, there was a problem of what
to do with the 80,000 migrated files in 40,000
directories and the users’ non-migrated files.
Special software and scripts were written to
store the file inode data, parse the DMF data-
base, and interact with the tape storage system.
Design issues, problems to overcome, bound-
aries to cross, and the hard reality of experi-
ence will be discussed.
9A Performance 2:00
Optimizing AMBER for the CRAYT3E
Robert Sinkovits and Jerry Greenberg (SDSC)
AMBER is a widely used suite of programs
employed to study the dynamics of biomole-
cules and is the single most used application
on the SDSC CRAY T3E. In this paper, we
describe the cache and intrinsic function opti-
mizations that were taken to tune the molecu-
lar dynamics module of AMBER, resulting in
single processor speedups of more than 70%.
The implications of these performance gains
for biochemistry calculations will be briefly
described.
9B Operations 2:00IRIX/ Windows NT Interoperability
Hank Shiffman (SGI)
No man is an island, entire of itself. Similarly,
computing systems need to interact, to share
information, to cooperate in helping users do
their jobs. We’ll discuss the range of challenges
involved in integrating IRIX and Windows sys-
tems into one environment, a variety of solu-
tions to these challenges and ways to satisfy
the differing concerns of application users,
developers and system administrators.
9C Visualization 2:00Reality Monster Volume Rendering
James Painter, Al McPherson, and Pat McCormick(LANL)
Texture based volume rendering algorithms
can be used to exploit high performance graph-
ics accelerators such as the SGI IR (Infinite
Reality) for interactive volume rendering. A
single IR can interactively render a 64M voxel
data set (256^3). Working with SGI, we have
chained together multiple IR pipes in order to
enable rendering of even larger problems. With
16 IR pipes we have been able to render billion
cell data sets (1024^3) at approximately 5
frames per second. We have constructed an
I/O system that enables us to interactively
page through billion cell time histories at
approximately the same rate. This I/O system
is able to page texture data from disk at 5
Gigavoxels per second.

9B Operations 2:30An Examination of the Issues inImplementing the PBS Scheduler on a SGI Onyx2/ Origin2000
Sandra Bittner (ARGONNELAB)
Schedulers and supporting utilities are used to
automate resource allocation. Identifying those
resources, tracking their usage, and identifying
mechanisms to control their allocation without
causing the system to thrash or crash is a chal-
lenge. I will outline the solutions we imple-
mented and the obstacles we encountered
while rolling out the PBS scheduler and sup-
porting utilities on our Onyx2.

9A Performance 3:00Performance Characteristics of Messaging Systems on the T3E and the Origin2000
Mark Reed, Eric Sills, Sandy Henriquez, SteveThorpe, and Lee Bartolotti (NCSC)
Interprocessor communication time has a large
impact upon the scaling of parallel applications
with processor number. To assess the effective-
ness of the T3E and the Origin2000 in using mes-
sages to move data to remote memory, the per-
formance characteristics of PVM, MPI and
SHMEM are investigated and performance
curves for transfer time as a function of message
size are presented. In addition, latencies, band-
widths and the message size required to achieve
half of peak are reported. Performance is also
compared with a cluster of O2 workstations con-
nected via Ethernet. Differences for many types
of point-to-point calls are presented and dis-
cussed. A variety of collective communication
calls representing a diverse set of traffic patterns
is investigated and results reported.

9C Visualization 3:00Distributed Memory Octree Algorithms for Interactive, Adaptive,Multiresolution Visualization ofLarge Data Sets
Raymond Loy and Lori Freitag (ARGONNELAB)
Interactive visualization of scientific data sets
generated on MPP architectures is a difficult
task due to their immense size; adaptive mul-
tiresolution techniques are necessary to reduce
data sets while still providing adequate resolu-
tion in areas of interest and full resolution on
demand. Because these data sets are often too
large to fit into the memory of a serial visual-
ization engine, we use a parallel octree data
structure closely coupled to the application to
increase the speed of interactive visualization
of both structured and unstructured data sets.
In this talk we discuss the parallel octree data
structure, its creation using criteria such as
mesh feature size or data gradients to adjust
level of detail, and efficient parallel algorithms
for searching and manipulating the octree.

Richard Lagerstrom (SGI)
Each node of an SV1 cluster will have a local
UDB just as if it were a stand-alone system.
The assumptions of an SV1 cluster require that
much of the user information be consistent
among all nodes of the cluster. The Cluster
UDB feature provides commands and inter-
faces to make UDB administration global. This
makes it possible to enforce UDB consistency
within the cluster while accommodating nodes
with varying resources or designated func-
tions.

techniques to build spectacular graphics and
animations in 3D. In our particular research,
we made a visualization of a natural convec-
tion mixing flow, and this visualization permits
us to analyze, in a graphic way, our flow. Cal-

The NAS division of the NASA Ames Research
Center installed a 256 processor single system
image Origin2000 system, the first at a cus-
tomer site, during the latter half of October
1998. Due to the large number of processors,
the system exhibits different operational char-
acteristics than smaller Origin2000 systems.
The causes of the observed behavior are dis-

11C Visualization 9:30Animation of Hairpin Vortices in aLaminar-Boundary-Layer Flow Past aHemisphere
Henry Tufo, Paul Fischer, Mike Papka, and MattSzymanski (ARGONNELAB)
In an effort to understand the vortex dynamics
of coherent structures in turbulent and transi-
tional boundary layers, we consider direct
numerical simulation of the interaction
between a flat-plate-boundary-layer flow and
an isolated hemispherical roughness element.
Of principal interest is the evolution of hairpin
vortices that form an interlacing pattern in the
wake of the hemisphere, lift away from the
wall, and are stretched by the shearing action
of the boundary layer. Using animations of
unsteady, three-dimensional representations of
this flow produced by a vtk enhanced CAVE
library developed at Argonne National Labora-
tory, we identify and study several key features
in the evolution of this complex vortex topolo-
gy not previously observed in other visualiza-
tion formats.

11B Operations 10:00Site Planning for SGI Products
Jim Tennesen (SGI)
With the volume of system installations shift-
ing from liquid cooled mainframes to air
cooled racks, the considerations for data pro-
cessing facility infrastrutures are changing. In
general, site preparations for the air cooled sys-
tems are much simpler and less expensive;
however, as air cooled systems scale to hun-
dreds of processors in dozens of racks, the
cumulative air cooled load may overwhelm
data processing facilities which have tradition-
ally supported liquid cooled systems. The pre-
sentation will provide power and cooling esti-
mates for future products to provide the data
center operations people a view of the long-
term trends. In order to get as much out of this
session as possible, it would be beneficial for
the participants to know how much heat rejec-
tion to air and water their present facilities can
provide and to consider at what heat rejection
value it is desirable to have equipment cooled
by liquid versus air. I'll also cover the impacts
that are associated with having few main-
frames consuming considerable current at
medium voltage (400 to 480vac), 3 phase
power versus dozens of chassis consuming

current at lower voltage (180 to 240), single
phase power. I prefer this to be a session where
I will present the information in 10 to 15 min-
utes and spend the rest of the time discussing
the issues with the participants. This will allow
me to understand the customers’ viewpoints
and bring those back to SGI Engineering.
11C Visualization 10:00The Use of Virtual Reality Tech-niques in Industrial Applications

12 General Session 11:45New Techniques for High Perfor-mance Visualization
Jim Foran (SGI)
Visualization is a critical aspect in understand-
ing results from supercomputing calculations.
However, in many supercomputing environ-
ments, the visualization techniques used are
limited by the capabilities of desktop worksta-
tions and do not match the requirements of the
end user. This presentation describes several
new visualization paradigms that eliminate
obstacles to understanding, increase the
involvement of scientists and engineers in the
analysis of their data, and increase the value of
supercomputing and visualization assets to the
organization.
13 General Session 2:00“Honey, I Flew the CRAY”
Candace Culhane (DOD)
From 1994 to 1999, the Department of Defense
has supported multiple R&D contracts with
Cray Research and SGI, all in support of the
goal of demonstrating a supercomputer capa-
ble of operating in mobile environments.
These research efforts included the applica-
tion of new thermal management and packag-
ing technologies to achieve miniaturization of
a standard CRAY product, the J90 vector
supercomputer. The research prototype SOLI-
TAIRE and its host system was designed, built
and tested. Companion programs were target-
ed at further developing spray cooling tech-
nologies and investigating the design space
for ruggedized versions of the Scalable Node
(SN) and Scalable Vector (SV) product lines.
This talk will summarize the research pro-
grams, the experiences encountered along the
way, successes and lessons learned, and what
the future outlook for ruggedized high perfor-
mance computers is. A highlight of the talk
will be the recounting of the successful Jan 99
flight test of an alternate ruggedized version
of the CRAY J90.

existing vector processors. The talk will
describe the micro-architecture of the scalar
processor, the vector processor, and the custom
streaming cache.
16B Software Tools 9:00Panel Discussion: Is “write” still theBest Debug/ Performance AnalysisTool Available?
Guy Robinson (ARSC)
As many programmers know, there is much
activity aimed at creating debuggers and per-
formance tools to aid in code development.
However, the majority of programmers still use
write statements and human logic combined
with knowledge of the applications when find-
ing bugs or performance bottlenecks. This
panel’s members will discuss two questions,
why write statements are preferred and why
programmers should use a debugger/perfor-
mance analysis tool.
16A Performance 9:30Performance Tuning for Large Systems
Edward Hayes-Hall (SGI)
A set of strategies and methods of tuning use-
ful for large Origin systems will be presented.
This will cover existing mechanisms and the
means to monitor the benefits of the changes.
16A Performance 10:00High Performance Simulation of Magnets
Balazs Ujfalussy (ORNL)
This talk summarizes the computational
aspects of the computer code that received the
1998 Gordon Bell prize. The code shows near
linear scale-up to 1024-processing elements
(PE) and also achieved record breaking perfor-
mance of 1.02 Teraflops.
16B Software Tools 10:00The SGI Multi-Stream Processor (MSP)
Terry Greyzck (SGI)
The SGI Multi-Stream Processor (MSP) is an
innovative concept in supercomputer design.
Exciting new developments in compiler and
library technology, coupled with hardware
support on the CRAY SV1, allow immediate,
direct comparisons with wide-pipe long-vector
architectures, with a four gigaflop peak speed.
This talk covers how to compile and run on an
MSP, what code changes may be necessary, and
the current status of the compiler. Through
examples and anecdotal evidence, a strategy
for developers to harness the full power of the
MSP on the SV1 is presented.
